RIVET-CLOTH.

Specification of Letters Patent.

Original application filed November 20, 1912, Serial No. 732,427. Divided and this application filed March 22,1913. Serial No. 756,079.

To all whom it may concern:

Be it known that I, JEROME T. Rurracoon, a citizen of the United States, residing at- Millbury, in the county of lVorcester and State of Massachusetts, have invented a new and useful Rivet-Cloth, of which the following is a specification.

This is a division of my application Serial No. 732,427, filed November 20, 1912.

This invention relates to a cloth without pile having when produced on the loom, perforations therethrough arranged at intervals both longitudinally and across the goods.

The principal type of fabric to which this invention relates is the so-called rivetcloth which is used in the manufacture of rubber tires, but it is capable of use for the production of any such fabric.

The invention involves improvements in the rivet cloth itself, so that it can be made in such a manner that it will be a complete article as it comes from the loom thus eliminating the necessity of picking out all the warp and filling threads occupying the spaces which are to be left vacant.

Reference is to be had to the accompanying drawings, in which- Figure l is a plan of the fabric on the loom showing it as it appears immediately after the weaving operation; Fig. 2 is a simi' lar view of the fabric after the rods are withdrawn and the left-hand edge trimmed off, and Fig. 3 is a similar view of the completed rivet cloth.

So far as I am aware rivet cloth has been manufactured heretofore by weaving a continuous length of cloth and having the filling inserted continuously from end to end of a continuous warp, but the warp and filling in the places where the openings are to ap pear are of a different color from the main body of the fabric, and after the fabric is woven they are drawn out. This is an expensive method, involving not only a slight complication in the weaving, but especially taking considerable time in the drawing out of the colored threads, and the wasting of these threads. This invention is designed chiefly to avoid this waste by making the fabric originally with the openings therein, so that the threads will not have to be cut and drawn out, or at least only two will for each space, and also to provide a firm fabric.

Referring now to the drawings, the following arrangement is provided. First, the warp A is arranged to consist of a plurality of sections of main warp threads 0: arranged in a plurality of series of a given number of threads each, say for example, eight. These threads are separated by spaces substantially of the same width as the width of a section of these warp threads. At the edges of these sections are binding warp threads (1 which are smaller than the main warp threads and thus are capable of being more closely woven in and perform a func tion similar to the selvage in that theyhold the edges of the sections. Outside the main warp are two warp threads (L2, the purpose of which will be described hereinafter. The filling is woven into these warps in the usual manner the usual roller chain (not shown) being employed to operate the jacks, but one of the jacks operates only after a definite number of picks are made, as for example ten. This is arranged so as tobe actuated at regular intervals, as for example, at every tenth pick in the embodiment illustrated in the drawings. In other words when ten picks of filling have been inserted in the warp, means will be actuated to move the shipper handle and thus stop the loom. Then the operator inserts a rod 25 into the warp as indicated in Fig. 1.

As the cloth feeds over the breast beam the rods 25 are drawn out either automatically or by hand. It will be understood, of course, that these rods 25 can be inserted by the means which are employed for introducing pile wires in carpets, on carpet looms and the like, without departing from the scope of the invention as expressed in the claims.

Referring especially to Fig. 1 it will be seen that the filling B is woven into the fabric to form the usual filling strand 6 across the same, but that just before the loom stops, that is on the ninth pick inthis case, a loop 7) is formed on one side of the fabric around the side warp thread a It is then woven into the fabric and extends out on the other side at 7) around the other strand (0 Then it passes to the other side of the rod 25 which has been inserted and is woven in again forming a second loop 7) on the other side. It then continues to be woven in for the desired number of picks, for example, ten, when the loom again stops Patented Aug. 4, 1914;

and the next rod 25 is inserted. The fabric as -thus produced on the loom itself thus assumes the form shown in Fig. 1. Now as the fabric passes on, and preferably before the rods 25 are withdrawn, the loops Z) are out along the fabric at the side. This leaves the fabric when the rods are withdrawn in the form shown in Fig. 2.

For the purpose of insuring that the filling actually remaining in the fabric shall be firmly woven therein and not likely to spread out in the rectangular spaces to be left, an extra filling thread 5 is left on each side of each space. These are the ones which are now connected with the strands b and as their opposite ends are clipped it will be obvious that each pair of them can be drawn out simultaneously with great rapidity and without interfering with the strength and firmness of the fabric. In this way the expensive operation of clipping and pulling out by hand all the threads to form spaces in the cloth is, for practical purposes, eliminated and this reduces the cost of the material very essentially. On account of having the end strand that comes next to the rod drawn out the filling that remains is firm, secure and uniform. In this way this kind of fabric is inexpensively manufactured and is made uniform throughout as the hand operations are dispensed with. At the same time a fabric is secured which is an improvement over the old hand-drawn rivet cloth in the particulars above specified.

Although I have illustrated and described only a single embodiment of the invention I am aware of the fact that modifications can be made therein by any persons skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described but What I do claim is 1. A rivet cloth fabric comprising warps arranged in sets of equal numbers having uniform spaces between the sets, and sets of filling threads interwoven with the warp threads and spaced from each other to provide rectangular openings through the fabric free from both warp and filling, each set of filling threads being cut on at one edge of the fabric at the end of the space, all the filling at the other edge of the fabric form ing complete loops around the edge warp thread.

A rivet cloth fabric comprising warps arranged in sets with spaces between each two adjacent sets and sets of filling threads interwoven with the warps and spaced fro-m 0 each other to provide rectangular openings through the fabric free of both warp and filling, the filling threads at the edges of said sets of filling threads extending beyond the opposite edges of the fabric to form 5 loops.

3. A rivet clothfabric comprising warps arranged in sets with spaces between each two adjacent sets and sets of filling threads inter oven with the warps and spaced from 7 each other to provide rectangular openings through the fabric free of both warp and filling, the filling threads at the edges of said sets of filling threads extending beyond the opposite edges of the fabric to form a single my hand, in the presence of two subscribing witnesses.
